DISPLAY, TOUCH, AND STYLUS SYNCHRONIZATION
First Claim
1. A method for synchronizing a touch data acquisition process, a stylus data acquisition, and a display refresh process, the method comprising:
- synchronizing the touch data acquisition process to the display refresh process;
detecting a presence of a stylus signal and initiating a stylus data acquisition process when the presence of a stylus signal is detected;
synchronizing the touch data acquisition process to the stylus data acquisition process; and
synchronizing both the touch data acquisition process and the stylus data acquisition process to the display refresh process.

Abstract
A touch input device configured to synchronize a stylus acquisition process with both a touch data acquisition process and a display refresh process is provided. The touch input device can include one or more processors that can synchronize the stylus data acquisition process to the touch data acquisition process by coordinating stylus scans to take place in between touch scans. The one or more processors can also virtual data banks to synchronize both the touch data acquisition and the stylus scan acquisition with the display refresh process.

15. A non-transitory computer readable storage medium having stored thereon a set of instructions for synchronizing a touch data acquisition process, a stylus data acquisition process and a display refresh process, that when executed by a processor causes the processor to:
-
synchronize the touch data acquisition process to the display refresh process; detect a presence of a stylus signal and initiating a stylus data acquisition process when the presence of a stylus signal is detected; synchronize the touch data acquisition process to the stylus data acquisition process; and synchronize both the touch data acquisition process and the stylus data acquisition process to the display refresh process. - View Dependent Claims (16, 17, 18, 19, 20, 21)
